Abstract: 369,750. Heating water. FOX, C. E., The Vale, Carden Avenue, Brighton, Sussex. March 26, 1931, No. 9282. [Class 64 (i).] Part of the water from a domestic hot-water heating system is passed into an auxiliary boiler 1, Fig. 1, in the furnace of the main boiler 3 to generate steam which is conducted through a calorifier or steam kettle 9 to give a quick supply of hot water. The auxiliary boiler, which may consist of a number of coils or of a tubular casting, is connected by a pipe 10 to the upper end of the heating coil 8 and to the bottom of a chamber 4 depending from the upflow pipe 5 of the heating system. The lower end of the heating coil is connected by a pipe 11 to the top of the boiler 1. To heat the water in the calorifier, a valve 7 in the pipe 11 is closed. When the valve 7 is open, boiler steam flows through a pipe depending from the pipe 11 into the chamber 4 and is condensed. In a modification, the boiler 1 discharges into an expansion chamber and condenser 13, Fig. 2, consisting of an outer chamber connected across the inflow and outflow pipes 5a, 5 of the system. An inner open-ended compartment 14 communicates with the lower end of boiler 1 and terminates beneath a bell 15 at the top of the outer chamber. Steam enters the outer chamber beneath the bell through a pipe 16 and after displacing the water beneath the bell is condensed, water then flowing back into the boiler. The return tube from the heating coil may project downwardly into the boiler 1 which is closed at the lower end, the part of the tube within the boiler having a non-conducting covering. The return tube may be connected to the boiler 1 by telescopic or flexible joints.

Title: Improvements in and relating to electrolytic condensers
Filed: 1931-03-28
Abstract: 374,188. Electrolytic condensers. CONDENSER CORPORATION OF AMERICA, 259, Cornelison Avenue, Jersey City, U.S.A. -(Assignees of Danziger, H. I. ; 40, East 10th Street, New York, U.S.A.) March 28, 1931, No. 9502. Convention date, March 28, 1930. [Class 37.] An electrolytic condenser has a tubular container 20 of thin aluminium supported from the lower end with its axis vertical by forming the container with an integral screwed neck 37 which is passed through a hole in a base 38 and secured by a nut 39. Immersed in the electrolyte 25 is an electrode 26 comprising a spirally wound aluminium strip coated with a thin film of electrolytically-deposited material serving as a dielectric. This electrode is carried by a conducting rod 27 which is tapered at its lower end and extends through the neck 37, where it is secured by a nut 31, its lower end serving as a terminal. The rod 27 is insulated from the casing by means of an insulating sleeve 29, flanged to form a washer at its lower end. This sleeve extends upwards for a considerable distance to prevent shortcircuiting by sediment 36 which may be deposited from the electrolyte. The top wall 21 of the casing has a vent 24 which is sealed by a removable rubber cap with a pinhole, to allow escape of excess vapour. Instead of a screw and nut fastening, the rod 27 may be held by expanding its lower end. Alternatively the rod may be of uniform diameter and held by spinning a ring 48, Fig. 4, around the sleeve and spinning the neck inwardly at its base 50. In modifications the neck 37 is split and tapered externally so as to grip the sleeve 29 when a nut is screwed up. In another modification the lower end of the rod 27 has an axial screwthreaded bore and is split so that it is expanded by the insertion of a screw. The bottom of the casing may be formed of an insulating part 94, Fig. 11, moulded into a metal ring 95, or the entire bottom may be moulded from insulating material. Two or more electrodes, each supported on a conducting rod, may be arranged in one container. Semi-liquid or jelly-like electrolyte may be employed instead of liquid. The lower portion of the rod 27 mav be coated with enamel or varnish as a further protection against corrosion. The protective sleeve 29 may be formed as an electroplated layer of rubber, celluloid, &c.

Abstract: 916,499. Electrophotographic production of printing plates. DELMONT Ltd., S. R. March 23, 1959 [March 24, 1958 ; Dec. 5, 1958], No. 9996/59. Drawings to Specification. Class 98 (2). [Also in Group XVI] A method of manufacturing printing plates comprises producing an electrostatic image on a continuous film of a photo-conductor substance substantially free of impurities and without bonding agents, which substance is applied to a base, developing the image, dissolving the photo-conductor substance, in areas not protected by the developer, in a solvent which does not attack the base or the developer, and treating the base where not protected by the photoconductor substance, the remaining photo-conductor substance acting as a resist for the subsequent treatment. A printing plate is formed by coating a zinc or magnesium block with a photo-conductive layer such as amorphous selenium, forming a developed electrostatic image thereon, dissolving out the photoconductive material where not protected by the developer with carbon disulphide, and etching the metal where now exposed with dilute nitric acid. Alternatively, the assembly with the developed image is exposed to infra-red radiation, which changes the selenium from the amorphous into hexagonal or crystalline form which does not act as an etching resist. The developer may contain radiation-absorbent particles, in which case the selenium is changed in the image areas, or may contain radiationreflective particles, so that the non-image areas are affected. Alternatively, the unchanged selenium can be dissolved away in carbon disulphide, and an etching solution used which does not attack the changed selenium. In another form, a photo-sensitive plastic plate is provided with a selenium or anthracene sulphur photo-conductive coating, on which the developed electrostatic image is formed to form a light mask. On exposure to light, the unprotected areas of the plastic plate are polymerized, and the unpolymerized parts etched away with alcohol or ethyl acetate and alcohol. The polymerizable element may comprise nylon glue. Polymerization may also be by heat. An offset printing plate is made from a steel base sheet coated with copper, then with chromium. The electrostatic image is formed and developed on a selenium coating on the copper, the unprotected selenium removed, and the chromium etched away where the selenium has been rembved. After removing the remaining selenium or developer, there is left a bimetallic plate.

Title: Process for injection of different materials primarily gases into hot melts
Inventor: BATES KENNETH W
IPC: C21C7/072
Filed: 1987-02-18
Abstract: Gas injection into a metal melt, accompanied if desired by powdered or solid treatment substances, is by way of a nozzle (14) inserted into the wall (12) of a melt-containing vessel (10). The nozzle bore (18) initially has a stopper (20) at its inner end and a delivery pipe (24) smaller than the bore (18) is movable therein. Before injection, the pipe (24) and bore (18) adjacent the stopper (20) are cooled by gas. By thrusting the pipe (24) against the stopper (20) while sufficient gas flow and pressure is maintained, the stopper is dislodged and the gas will enter the melt as a jet which leaves the pipe (24) at a velocity equalling or exceeding Mach 0.5. Melt enters the clearance between the pipe (24) and bore (18) but, due to the pre-injection cooling, rapidly freezes locking the pipe safely in the bore.
